Subject: mn10300, c6x: CONFIG_GENERIC_BUG must depend on CONFIG_BUG
CONFIG_BUG=n && CONFIG_GENERIC_BUG=y make no sense and things break:
In file included from include/linux/page-flags.h:9:0,
from kernel/bounds.c:9:
include/linux/bug.h:91:47: warning: 'struct bug_entry' declared inside parameter list
static inline int is_warning_bug(const struct bug_entry *bug)
^
include/linux/bug.h:91:47: warning: its scope is only this definition or declaration, which is probably not what you want
include/linux/bug.h: In function 'is_warning_bug':
>> include/linux/bug.h:93:12: error: dereferencing pointer to incomplete type
return bug->flags & BUGFLAG_WARNING;
